A hydrogen atom forms one bond, an oxygen atom forms two, and carbon forms four bonds.
hope it's help you ok have a good day
Answer:
Explanation:
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
In 1897, J.J. Thomson discovered the electron by experimenting with a Crookes, or cathode ray, tube. He demonstrated that cathode rays were negatively charged. In addition, he also studied positively charged particles in neon gas.
Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. Rutherford designed an experiment to use the alpha particles emitted by a radioactive element as probes to the unseen world of atomic structure.
The Bohr model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons. Bohr was the first to discover that electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.
Explanation:
1) Reaction between nitrogen gas and oxygen gas.
According to reaction, hen 1 mole nitrogen gas reacts with 1 mole of oxygen gas it forms nitrogen oxide gas as a product.
2)reaction between nitrogen oxide and oxygen gas.
According to reaction , when 2 mole of nitrogen oxide reacts with 1 moles of oxygen gas to form 2 moles of nitrogen dioxide.
Answer:
Explanation:
The new product is a compound which is a product of combination of two reactants. This form of reaction is called Synthesis or combination. It involves the formation of compounds from the union of constituent elements in a reaction.
A compound is composed of two or more kinds of elements that are joined together in a definite grouping.
